EMC TESTING: EVENTS


EMV 2021 goes digital


The annual German EMC event, ‘‘EMV’’, will take place on-line this year with 35 workshop sessions planned


T


he exhibition circuit has ground to a halt during the past 12 months and ongoing government policies around the world have shut down this year’s season as well. This


hiatus hasn’t put the organisers of EMV off though as the annual German event for EMC professionals has now gone digital. The event will take place from March 22-26 and virtual attendees will be able to compile their own event agenda and training sessions from the main topics covered during the event. The organisers have thus extended this


WORKSHOPS


❱❱ Understanding EMC/radio/ automotive standards


❱❱ Tuesday March 23; 09:00-12:00 ❱❱ Dr Diethard Hansen, EURO EMC SERVICE (EES) Dr Hansen Consulting, Switzerland


❱❱ This session will provide advanced knowledge of the latest EMC/radio/wireless and partly automotive (ESA) lab ‘‘EM-Field’’ testing of EU CE product compliance. It is aimed at EMC professionals engaged in product approval, EMC/wireless testing and electronics design/development. There will be a focus on test standards,


calibration, instruments, field-sensors, antennas and EM test site-related set-ups, such as absorber lined chambers/ qualification testing for radiated emissions (RE) and immunity (RI). Case studies for commonly used lab equipment will be shown, including wrong applications. The speaker will cover various antennas for radiated emissions and immunity like Bicone, Log-Per, stacks, horns and TEM wave guides. Antenna factors vs. frequency, radiation pattern and sensitivity need to correspond with the chosen radiated emissions standard and test distance.

❱❱ EMC filters, design, applications and tricks


❱❱ Tuesday March 23; 14:00-17:00 ❱❱ Prof Dr Frank Leferink, University of Twente, The Netherlands


❱❱ Aimed at electronic design and systems engineers, this workshop starts with basic filtering concepts, common mode, differential mode and normal mode (asymmetric, symmetric and non- symmetric) and impedance mismatch. How to select filters and what the


important parameters are will be discussed. There will be a demonstration of the effect of Cx capacitors on mains or on the EUT side, the effect of multiple filter stages, virtual ground in three-phase filters. Input or output filters for frequency


converters (dV/dt, sine filters and EMI filters) will also be a topic.


❱❱ Radio modules and integration into electronic equipment for FCC, ISED and RED


❱❱ Wednesday March 24; 10:00-13:00 ❱❱ Michael Derby, Element Materials Technology, UK


❱❱ Aimed at EMC and radio test labs,


manufacturers of radio modules and makers wishing to install radio modules into their products, this workshop covers testing and regulatory requirements for radio modules for compliance with FCC, ISED and RED. It will cover the process of approvals for the module and also the requirements for anyone installing a radio module to create connected technology. Equipment manufacturers and test labs are faced with radio modules already certified for the USA and Canada, and CE marked for the EU. This presentation explains the compliance status of the module and what the installer and test lab must do when the module is installed into other equipment. This will be a mixture of EMC and radio testing, and regulatory compliance.


❱❱ EMC in electrical drive systems ❱❱ Wednesday March 24; 14:00-17:00 ❱❱ Prof Dr Frank Leferink, University of Twente, The Netherlands


❱❱ Power drive systems (PDS) are used in all kinds of mechatronic applications for speed control. The drawback is that high electromagnetic interference levels on power lines, motor cables and via radiated


year’s event to cover five days, allowing more diverse combinations of specialist workshop topics with fewer overlaps. And though human interaction might be curtailed, the flexibility of the digital format means the event can be integrated into the normal working day of attendees.


EVENT FORMAT The organisers have taken advantage of video conferencing, interactive on-line sessions and social media to streamline the delegate’s visit. For example, attendees will receive suggestions for best matches or
